The Magnus Stinger broadheads will fly as well as, or better, than any mechanical broadhead made today. Its superior main blade is made from knife-grade stainless steel. It comes razor sharp right from the package.
 
This is a four blade broadhead. Available in 125gn or 150gn. 
 
As with all Magnus products, the Stinger Killer Bee carries a Lifetime Replacement Guarantee. If you damage one, take a clear photo and email it to customerservice@magnusbroadheads.com.
